Physical answer: p 1. Vibrating vocal cords, air wind 300, high sound source, in-ear propagation, environmental protection, impact on rest and learning AADBBAC P3, vibrating solid loudness sound, noise loudness sound, acoustic energy 476 vibrating loudness sound, vibrating loudness sound, ACCDB alarm clock stopped ringing, Sound can't be transmitted in vacuum. It travels in a straight line about 640m light-years per second. 3* 10. The eighth-power solar eclipse with slow reflection of 6 0 120 degrees and 4.05 * 10 is drawn by ADAA, and the reversible reflection angle of the straight-line lunar optical path is reduced by P7 60 degrees, 0 degrees and 40 degrees.

The refraction diagram of plane mirror to imaging light is abbreviated as P 1 1 45 degree 60 degree concave convergent convex mirror. Linear Propagation of Divergent Light The sun's three primary colors, red and black DADABD light, are obliquely incident into different media from the air, and the different refraction angles are smaller than the incident angle, because the candle will change when burning 13. The vertically magnified virtual image is nearly 30 convex 80 solid 10. The same height is compared with 0. Away from convex convergence BBACAA. The convex lens screen 10 on the same horizontal plane narrows the inverted image to the left, enlarges the inverted image to the right without imaging, enlarges the focus of the virtual image vertically, cuts the ice into convex lenses with a knife, gathers sunlight and catches fire. P 15 is transparent and larger than 2f. Inverted image reduces the thickness of the lens retina of the real camera, and the anterior concavity is 40cm. Guess 3 is correct.
